I need some of the foil tape that is used to connect AC ducts. What would I look for on ebay? I need to put some sort of sealant between sheets of steel roofing to cut down on air loss. In some places, the sheets are at a ninety, so it will take a lot of weaving the tape around. Do you think the tape would last very long in that application? Surface temperatures on it will be 140+ in the summertime.
